Patent JP-H0447822-A (JP)
Title: Synchronization changing system
Inventor: OOTAWA MASAYUKI
IPC: H04J3/06
Filed: 1990-06-15
Abstract: PURPOSE:To prevent a circuit from being complicated and the scale from being enlarged by inputting a digital signal train and a clock respectively to an active line and an auxiliary line, and switching an active digital signal and an auxiliary digital signal without instaneous interruption after executing network synchronization based on a reference clock. CONSTITUTION:A frame synchronizing circuit 2A, which inputs a received and inputted digital signal train 24A and an input clock 25A, establishes frame synchronization to the signal 24A and outputs a frame pulse 26A having the same cycle as a signal 23. The phase of the signal train 24A and the pulse 26A are absorbed by a phase absorbing circuit 3A. A signal train 27A whose phase is absorbed is lined up with a pulse 28A whose phase is absorbed as well. Since the phase is not managed to the signal 23, however, frame matching, namely, lining-up is executed by a frame matching circuit 29A. By executing such a lining-up to both an active lines 11 and an auxiliary line 12 in the signal 23, according to a switch control signal 30, the active line and the auxiliary line can be switched without instaneous interruption.

Title: Apparatus for fabricating multiplex winding coil
Inventor: MATSUMIYA YASUNORI
IPC: B65H81/08
Filed: 1978-12-21
Abstract: PURPOSE: To equalize the interlayer stress of a multiplex winding coil by supplying a wire coated with differently thick insulating coating to a bobbin to thereby form the multiplex winding coil having different covering thickness.  
     CONSTITUTION: A wire 2 is supplied from a wire drum 17 to a bobbin rotated to csst an insulating coating by a covering mechanism 21. The wire 2e is passed through a rotary plate 23 rotating around a hollow shaft 23a as a center in the mechanism 21. A tape holding plate 35 for supplying a tape 6 together with the rotary plate 23 makes a roller 37 rotatably contact with a guide ring. Thus, the tape 6 is wound on the wire 2. The thickness of the tape 6 is altered by varying the angle α, which is controlled by driving a motor 27 to thereby rotate a feed screw 28 to feed the rotary plate 23 toward the direction as designated by an arrow 44. Thus, the wire altering the thickness of the insulating coating periodically is automatically supplied.

Title: Constant speed running control method for vehicle
Inventor: KAWANO ATSUHIRO
IPC: F02D45/00
Filed: 1989-06-20
Abstract: PURPOSE:To enhance the reliability of the control by implementing the operation of opening or closing a throttle valve at a constant speed when the voltage value as output from a throttle sensor indicates abnormality, and continuing the car speed control with this output voltage value if the car speed is nevertheless over a pseudo car speed in a width greater than a specified value. CONSTITUTION:A throttle valve 6 provided in a suction passage 10a is opened or closed by a drive motor 5, which is controlled by a controller 3 on the basis of the car operating condition. At this time, the voltage signal emitted by the throttle sensor 14 is sampled at certain intervals to permit the sensor 14 to judge abnormality on the basis of the deviation of the present voltage value from the corresponding previous value. In the event of abnormality judgement, the throttle valve 6 is opened or closed at a certain constant speed. When the car speed is over a pseudo car speed value corresponding to the target voltage value in a width greater than a specified value until the specified period of time has elapsed since the abnormality was sensed, it is judged that the voltage signal from the throttle sensor 14 is normal, and the car speed control is continued.

Filed: 1993-06-28
Abstract: PURPOSE:To surely stop an eletric motor at the time of rolling in order to lessen the burden to wire and thus provide an elevator with improved safety. CONSTITUTION:When rolling occurs at the time an elevator goes up, a swinging part swings and tilts due to the rolling of the wire and an operational part presses a switch lever of a microswitch SW1 and shuts the microswitch SW1. Due to the shutting of the microswitch SW1, current flows in a relay coil Ry2L and a relay contact point Ry2S is closed and the relay coil Ry2L is protected by self-protection. A relay contact point Ry2S1 is opened and an electric motor 5 is stopped. The wire is prevented from damage owing to entwining and twisting of the wire due to the rolling of the wire. Since the relay contact Ry2S is protected by self-protection, it is prevented that the electric motor 5 is operated again after the rolling stopped and especially that the electric motor 5 is stopped and operated repeatedly.

IPC: B29C48/03
Filed: 1980-11-11
Abstract: PURPOSE:To avoid the stagnation of the resin in a valve casing and the leakage of the  resin to the outside of a system, by forming curved concave parts whose radius of  curvature is slightly larger than the radius of curvature of the main body of a cylindrical valve so that said parts face to each other in a wall part of a flow path. CONSTITUTION:The mainbody 10 of the cylindrical valve is enclosed in a cylinder path  20 which is vertically provided in a valve casing 18 so that the valve body can be freely moved up and down. A horizontal resin path is provided in the valve casing 18 and  communicated to the cylinder path 20. A part 24, in which the cylindrical valve main body 10 is lowered, is a path having a square cross section. The curved concave parts  26 whose radius of curvature is slightly larger than the diameter of the valve main  body 10 at the central part so that the parts 26 face to each other and the curved gaps  are formed between the valve main body 10 and the inner wall of the path 24 when the valve main body 10 is lowered. When the valve main body 10 is pushed into the  resin path, the resin always passes through said curved gap. Therefore the partial  stagnation of the flow of the resin is avoided, and troubles and the like in appearance and strength due to burning of the resin, discoloration of the extruded material,  and change in material quality can be avoided.
